Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 242 Issued at 2200Z on 30 Aug 2011
IA.  Analysis of Solar Active Regions and Activity from  29/2100Z
to 30/2100Z:  Solar activity was low. Region 1274 (N19W59) produced
occasional B- and C-class flares as it developed from a plage region
to a six-spot Bxo group. The largest of these was a C1/Sf at
30/0312Z. Three new regions were numbered: 1282 (N24E01), 1283
(N12E71) and 1284 (S19W57); all of which were small and
simply-structured. There were no Earth-directed CMEs observed during
the period.
IB.  Solar Activity Forecast:  Solar activity is expected to be low
through the period (31 August - 02 September).
IIA.  Geophysical Activity Summary 29/2100Z to 30/2100Z:
Geomagnetic field activity was at mostly quiet levels with unsettled
periods observed at high latitudes.
IIB.  Geophysical Activity Forecast:  Geomagnetic field activity is
expected to be at mostly quiet levels through the period (31 August
- 02 September).
